MACHINE FOR UNFOLIDING AND ROLLING CLOTH.

To all whom z't may concern.'

Beit known that I, BENJAMIN l/VEINBER`- GER, a citizen of the UnitedStates, residing at the city of St.Louis and State of Missouri, haveinvented a new and useful Machine for Unfolding and Rolling Clot-ln'ofwhich the following is a specification.

This invention relates to machines for unfolding and rolling cloth.

At the present time various kinds of cloth are folded longitudinally androlled or reeled upon boards to provide the bolts, inv

which form the cloth is distributed tothe dealers and to garmentmanufacturers.

My invention relates to mechanism for unfolding the cloth as it isremoved from the bolt and rolling the cloth upon a roll to enable thecloth to be cut into proper lengths rapidly and with facility.

.lhe object of the invention is to provide a machine of the charactermentioned, comprising a revoluble support for the roll or bolt of cloth,in combinationwith a roll adapted to have one end of the cloth connectedthereto, mechanism for revolving the roll, a triangular element betweenthe roll and the bolt of cloth over which the cloth is drawn andunfolded as it passes toward the roll, and tensioning devices for thecloth between the roll and the unfolding device. l

In the accompanying drawings, in whicha preferred embodiment of theinvention is illustrated, e

Figure l is an end elevation of the machine.

Fig. 2 is a side elevation looking toward the unfolding device. e

Fig. 3 is a view illustrating a longitudinal guiding slot in the rollfor guiding the knife whenV the cloth is cut in lengths. l

Fig. 4 is a similar view illustrating an oblique guiding slot in theroll for guiding the knife in cutting thev cloth obliquely.

Fig. 5 is a detailedtview illustrating a clamp which may be employed forconnecting one of the ends of the cloth to the roll.

Fig. 6 is a perspective view illustrating in detail a part of the guidefor the cloth as the cloth passes toward the unfolding device.

The machine illustrated comprises a frame composed of a stationaryupright 1 and an adjustable upright 2 movabletoward and away from theupright l. The upright 2 maybe held inconnection with the supportingbase by a clamping Vbolt 3 passing Specification of Letters Patent.

through an angular extension of the upright 2 and through a slot in thesupporting base. The uprights 1 and 2 constitute supports for upholdingthe bolt of cloth which is to be unfolded and rolled. Y

The device for upholding the bolt of cloth includes preferably ametallic frame 4which may be constructed of small rods or spring wire asshown and provided with extensions adapted to seat in bearingsin theuprights 1 and 2, as will be understood by referencev to Fig. 1. rTheframe 4 may be easily inserted in the bolt of cloth by first removingtherefrom the usual board upon which the cloth is Wound, and insertingthe frame 4 in the space previously occupied by theV board. After thebolt of cloth has thus Vbeen placed upon the frame 4, the latter may bemounted in the bearings in the uprights 1l and 2 kand the free end ofthe cloth passed upwardly between guides below the unfolding device.rl`he guides for the cloth comprise two members 5. One end of each ofthe members 5 issupported by the upright l and the opposite ends thereofare ymounted. in a support 6 in which they are retained in spacedrelation by a removable key 7 seating in the slot in which the members 5extend.

By -reference to Fig. l, it will be observed that the support 6 isspaced from the upright 2, thus permitting the latter to be moved todifferent adjustments asrequired to accommodate and support bolts ofcloth of different widths.

The unfolding device includes a triangu' larl guide 8 secured` to asupporting frame `9 and extending obliquely downwardly there.- fromtoward the guides 5, so that as the cloth is drawn between the guidesone fold of the cloth will pass at one side of the guide 8 and the otherfold of the cloth will` have illustrated a motor 12 driving a belt 13passing over a pulley 14 in connection with the-roll 10. The end of thecloth which is drawn over the upper horizontal edge of the guide 8 issecured in connection with the roll 10 by releasable clamps l15, so thatas the roll turned the cloth will be .wonndmlvinglthe actuating roll todraw the cloth thereon.

1n Aorder tol prevent Ybuckling of the cloth,

I provide a series'of tensioning guiding rrods 16 supported between theroll 10 andthe un-Y folding guide 8, and between which the endoftheeloth ispassed before it is connected. to 'the' roll'. Will bedrawn between the rods 16 thus holding the cloth straight andmaintaining it at proper tension.V

transversely :While on the roll andrto constitute @a guide-forthe-knifef or cutting imple- ;ment, the roll is formed Withalongitudinal ser/vevfasa guide )for thelmife.

lSince-the :roll 10 isquitelarge and the cloth is Wound closely thereon,the variation inthe rlength ofthe layers of cloth is sovery slight thatit is immaterial.y 1n practice, "therefore, the -roll- =is utilized `rtovplace the 'cloth in layers and since ythe7 :areso nearly of uniformlength they are-infact used las I measured layers. v

vFromfthe foregoing description,it Willbe readily understood lthat thebolt is placed Within vthesupporting frame with -the fold of f the;clothy directly below the extremity of the -triangular guide S and Ithatthee'nol-v o'fthecloth is-passedoverfthe horizontal 11p-'- peredgeoftheguide and thence 'between the rodsI 19 and Vto the roll, to 4which"the clothiis connected. Rotation of theroll vin the Vdirection of thearrow `in YFig.v L1 -Will- Wind the fcloth thereon, While the devicesbetween-therolland'the bolt of cloth `serve first to unfold the cloth,and-then to give it the iproper tension preparatory' to being cutintomeasured lengths as determined by theslots Ainl-the roll, or otherwise.
